UQMNWRREK w N aca Lseo extending spring saddles, il), on the tops ot which the spring hands, 9, are support ed, and from which the weight is applied the driving boxes is applied to and acts thereon uniformly throughout its length. The spring seat, 10, is, in this instance, shown as extending integrally'from the spring otone ot the driving boxesot an axle to the spring of the other, and, also, having the spring bearings, 10a, termed integral with it. Such speciiic construction is not, however, o the essence et my invention, in 'dependent spring seats, may, as hereinafter specified, he provided, and tlie spring bearings, lOinay be formed septrat Lely 'from the spring seat, and may be duplicated tor veach spring, so as to apply the 'weight to the driving boxes in two parallel planes, located at' substantially `equal distances trom their ends. p

Figs. 5 to 8 inclusive illustrate a inediti.- cation of structural detail, embodying the same essential operative features the ein.

bodiment zot the invention iirst described,

and varying therefrom only as to the specie form of the spring saddle and spring bearings. As shown in Figs. 5 and t3, the spring bearings, l0, are termed separately from the springseat, l0, and are detachably secured thereto by bolts, l0", said bearings' abutting on the driving boxesjmidway of their length, as in the instance rst described. Figs. 7 and 8 show the spring seat as a composite three part structure, comprising two independent end seat sections proper, l0, 10, on which the spring bands rest, each ot said sections having a downn wardly extending spring bearing, 10a, which abuts on the driving 'box above" which it is located, adjacent to the outer `end thereof. Each of the seatfsections abut, at its inner end, on-the adjacent `end or a transverselyv extending connecting section, fllc, having supplemental spring bearings, i106, extending downwardly trorn"its lower side and abutting on the adjacent driving boxes at substantially the same distance frein 'their inner ends as the spring bearings, ld, et' the seat sections, l0, are spaced ltroia their outer`- ends. The weight transmitted to the driving boxes through the springs, 9,V 'is thus applied to the driving boxes unijtormiy throughout their length.

In the further modication illustrated in Figs. 9 to 12 inclusive, the springs,9, ot each driving axle are spaced more closely to get-her than in the instances previously described, their longitudinal central planes being located ata less distance apart than those et the side 'trame members, and each spring is supported on a spring seat, 10, having two. downwardly. extendingv spring bearings, 10a, which abut on the driving box above which the spring seat is located, at substantially' equal distances trom its ends. The spring hangers, 9b, at each end of the springs of the driving boxes of each axle, are coupled one to the other by a transverse connecting bar, or a pair of connecting bars, ll, to which they are pivoted by pins, 11a, and said connecting bar is `coupled by pins, 1lb, to lower spring hangers, 9, the lowerv ends of which are coupled l,to equalizers, 9d, or'to the trame rails, as'the driving wheel arrangement may require. The independent spring'seats, 10, ot' the opposite driving boxes, are thereby connected for the transmission of strain from one side frame noem'n oer to the other, as in the instances before described. r

lt will be obvious that various structural I modiiications, embodying .the vspirit and lop'- erative principle ot my invention, 'may be made by the sltilled constructor, without de parture therefrom, and fl do not therefore limit my invention to the specific structural embodiments herein set forth.
